j frolaims'. (01. 215-11 I My invention relates bottlesj andparticularly to bottles from the-necks oflwhich liquid-is bottles; andit also relates to bottles from which liquid is to be poured in a steadystream, un.- currents entering-at the bottle broken by air mouth; 1 lThis invention is a modification ofv the invention for which I filed anapplication forpatent on October 22,1942, Serial 'No. 463,009; now

Patent No. 2,342,722, February 29, 1944; in which application Idescribed a bottle having on its body and near its base a projectinghollow boss form ing an air inlet to the bottle, the said boss having onits side a slot affordingapassage for air into the bottle.

In the present application I describe a bottleof the boss and into'thebottle. The opening in the side of the boss may be in the form of around hole; of somewhat larger size than the perforation through theside wall of the closureyor it may be in the form of a slot throughtheside wall'of the boss; or it may be in the form-of a flute within thelimits of which a hole is formed into the inside of the boss. whenthehole through the side wall of the boss is elongated, as in theform ofslot or'flute, it is easier to register with it the small perforationinthe side wall of the closure. i'

A' special feature. of. my present'inventionis that the elastic closurefits snugly aroundthe boss on the side of the bottle, yet not so tightlythat it maynot be twisted or turned on the boss;

and further: that the closure is punctured by a smal1hole ora slit inits side; which puncture 'niay, when the closure is turned on thevboss,be

made to register with an opening through the side of the boss; and socommunicate with the inside of the boss and of the bottle. 1

- In Figure 1: The numeral 2 indicates the glass of; the nursingbottle,which is shown laid upon its side. On the opposite side of the bottlethere is formed an annular boss 4, through which passes a largevent-hole 6 into the inside of the bottle.

2; see Figures 2 to 7 inclusive. Thetbottle is shown in the positioncommonly .used when feeding an infantyand it is obvious that if no airwere allowed to enter the end of the bottle-a partial vacuum would beformed in the bottle'as liquidis drawn from the mouth of the bottle;

and when the bottle is being used for nursing, with nipple, .not shown,the vacuum within the bottle will cause thenippleto collapse and to Iimpede the flow of liquid from the mouth of the bottle. 1

The object of this invention-is toprovide a nursing bottle in which thispartial vacuum-may be reduced without introducing any unsanitarymeans;which bottle may be with certainty cleaned and sterilized; which shallbe inexpensive and durable; and which may be operated and held by onehand of the nurse in attendance.

To prevent leakage: bossidis closed by an This closure may be othermaterial which is waterproof, and which shall be suficiently elastic tofit the boss snugly,

elastic ca or closure II].

to cover the bossso that no liquid may leak from the inside of thebottle when the bottle is stood on end.

In the side of the closure I0 there is made a puncture [2. This puncturemay be in the form of a small hole, as in Figures 2, 3, 4, and 5; or inthe form of a small slit, as in Figures 6 and 7.

In Figure 6 this slit is shown as if having an inside of the boss thanon the outside so that v The bore 6 through the made of rubber or ofanyliquid lodging against the cap Ill may drain back into the bottle.Air is admitted to the inside of the boss and bottle by turning the capill on the boss 4 until the small puncture l2 registers with the hole[4. Air will then pass into the interior of boss and bottle through thepuncture l2 and the hole M.

In Figure 4 the outside of the boss is shown fluted at I 6. It is alsoshown as perforated at 18 within the boundaries of the flute (6. Whenthis perforation I8 is not used with the flute, the air channel to theinterior of the boss may be made by means of a depression 20 in the bosswall at the upper end of the flute. The object of the flute i6 is togive a greater range to the registering of the puncture in the cap withthe hole It; for obviously, though the puncture in the cap 12 may notregister directly over the hole I8, it will register with the flute, bywhich the air will travel to the hole I8. A cross section through theflute l6 and hole I8 is shown in Figure 5.

As stated above: The puncture l2 in the capclosure in may be in the formof a small hole, or of a small slit. In Figure 6 I have shown, in

k elevation, a cap-closure snugly covering a boss;

in which cap-closure there has been made a small slit l2. Beneath theslit is shown, in the wall of the boss a flute or even a slot 24. In thecross section in Figure 7 this opening in the wall of the boss is shownas a slot, which is cut or cast through the side wall of the boss. Whenthe slit in the cap-closure is made with contact ing side walls therewill be little or no leakage through theslit when'th'e bottle is placedon end; and when in the position shown in Figures 6 and 7 it may benecessary to press upon the capclosure at a point adjacent the slit toopen the said slit to admit air to the inside of boss and bottle.

Iclaim:

1. A nursing bottle having a boss formed on and extending from theoutside of its lower portion, and with a large vent-hole through thewall of the bottle and through the length of the boss for the passage ofair into the bottle and for cleansing and sterilizing operations; thesaid boss having an aperture formed in its wall to permit the passage ofair therethrough; in combination with closing means adapted to cover thesaid vent-hole and the said aperture and to yieldingly embrace the saidboss to normally prevent the passage of air between the boss and the0105- ing means yet permitting the moving of the closing means on theboss: the said closing means having through its wall a puncture which onmoving the closing means on the boss may be registered with the aperturein the wall of the boss.

2. -A nursing bottle having a boss formed on and extending from theoutside of its lower portion, and with a large vent-hole through .thewall of the bottle and through the length of the boss for the passage ofair into the bottle and for cleansing and sterilizing operations; thesaid boss having an aperture formed in its wall to permit the passage ofair therethrough; in combination with closing means adapted to cover thesaid vent-hole and the said aperture, and to yieldingly embrace the saidboss to normally prevent the passage of air between the boss and theclosing means, yet permitting the moving of the closing means on theboss; the said closing means having through its wall a puncture which onmoving the ciosing means on the boss may be registered with the aperturein the wall of the boss; the said boss being so located and so spacedfrom the base of the bottle that when the bottle is held in the palm ofthe hand the closing means may be manipulated by digits of the samehand.
